Table 2 lists the characteristics comparison between the proposed P-PoW
algorithm and the traditional PoW algorithm. In the PoW algorithm, the
trust level of block data is based on the total computational power
across all network nodes as it searches for the minimal hash value,
making its credibility strictly higher than that of the P-PoW algorithm.
On the other hand, the PoW algorithm leads to high energy consumption,
slow new block generation, and low data upload bandwidth due to
utilizing the total network computational power. The P-PoW algorithm,
conducting the minimal hash value search through local computational
power, has lower energy consumption, larger data upload bandwidth, and
the data receiver can verify the sender’s computational power through
the hash value, increasing the difficulty for data tampering.
Furthermore, P-PoW parallelizes the proof of work with new block data
filling, enabling real-time new block generation, suitable for real-time
electric power data transmission and other applications.
6. Conclusion
Based on the principles of the blockchain proof of work algorithm, this
paper proposes a parallel proof of work method. By parallelizing the
proof of work process with the new block data filling, the blockchain
system can real-time generate and transmit new blocks, overcoming issues
such as high energy consumption, slow new block creation, and low data
upload bandwidth.
The results of computer program simulation demonstrate that the proposed
parallel proof of work algorithm can be effectively applied to real-time
data transmission scenarios like electric power data transmission. While
enhancing data transmission trustworthiness, it retains functions such
as timed data uploading and real-time data retrieval. This offers a
feasible solution to the data security transmission problem in the
digitization and intelligent development of the power grid.
